Thermodynamic Studies of Hydrochloric Acid in HAc-H2O Systems

Abstract

Abstract: By using a glass electrode and a numerical ionometer, an EMF measurement for the cellglass (H⁺)|HCl(m), HAc+H₂O|AgCl-Agwas performed in a series of HAc-H₂O mixed solvents with the concentration of HCl as 0. 020, 0. 040, 0. 060, 0. 080 and 0. 100 mol/kg-solvent. The average activity coefficients for HC₁in the mixed solvents and the standard transfer free energy for the electrolyte from water to the mixed solvents are evaluated, and a discussion about the results is given briefly.

Key words: Water-acetic acid system, Electromotive force, Activity coefficient, Transfer free energy
